Teledyne API Model 200AU NOX Analyzer Instruction Manual, 02293, Rev. F

5.5.1 Setting Up the RS-232 Interface

The baud rate is set from the front panel by SETUP-MORE-COMM-BAUD. Select the baud rate appropriate for your application, 300, 1200, 2400, 4800, 9600, or 19,200. It is important to note that the other device must have identical settings in order for the communications to work correctly.

Second is physical wiring of the analyzer to the other unit. We have incorporated into the Analyzer LED's that signal the presence of data on the communications lines, and also switches to easily re-configure the analyzer from DCE to DTE if necessary. In addition the front panel diagnostics allow test data streams to be sent out of the port on command. This flexibility and diagnostic capability should simplify attaching our equipment to other computers or printers. If problems occur, see the Troubleshooting Section 9.3.2.

Setup from the Front Panel

There are 2 additional RS-232 setups that can be done via the front panel.

1.Set the instrument ID number by SETUP-MORE-COMM-ID, and enter a 4 digit number from 0000-9999. This ID number is part of every message transmitted from the port.

2.Set the RS-232 mode bit field in the VARS menu. To get to the variable press, SETUP- MORE-VARS, then ENTR and scroll to RS232_MODE, then press EDIT. The possible values are in Table 5-10.

Table 5-10: RS-232 Port Setup - Front Panel

Decimal Value

Description

1

Turns on quiet mode (messages suppressed)

 

 

2

Places analyzer in computer mode (no echo of chars)

 

 

4

Enables Security Features (Logon, Logoff)

 

 

8

Enables API protocol and setup menus

 

 

16

Enable alternate protocol

 

 

32

Enable multidrop protocol

 

 

NOTE

To enter the correct value, ADD the decimal values of the features you

want to enable. For example if LOGON and front panel RS-232

menus are desired, the value entered would be 4 + 8 = 12.
